With 2 pokemon running toxic, Forretress has no use running toxic spikes, and stacking them with spikes as your other moveslot doesn't sound like a good idea since 1 rapid spin or defog will get rid of all of them. You should teach Forretress volt switch so that it can bring in other pokemon safely with its low speed.

Personally, Forretress should just run stealth rock(you'd have to breed with crustle/dwebble though) since it's more reliable than setting up spikes as it's guaranteed to damage everything upon entry as well as dealing more damage due to typing weaknesses to rock. And because of that, you might as well not have to run stealth rock on Cobalion either.

Cobalion can just run the close combat and iron head you have, taunt is fine for utility since it ensures opposing stallers won't be able to spread burns(which is what Cobalion might lure in, since it can't be poisoned due to steel typing), and the last move can be something like swords dance, coverage moves or more utility moves. Volt switch is of course, still fine, if you wish to keep it on Cobalion. Since you're running volt switch on it, I'm assuming it's an offensive pivot anyway with that moveset your running. But as of now, it's fairly pointless to have volt switch on it since general threats such as fire types, bulky ground and water types that can switch into Cobalion comfortably, you have no confirmed way of handling them.
